		 *   They are only present when using a viminfo file viminfo-file.  Basically '0
		 *   is the location of the cursor when you last exited Vim, '1 the last but one
		 *   time, etc.  Use the "r" flag in 'viminfo' to specify files for which no
		 *   Numbered mark should be stored.  See viminfo-file-marks.
